COMBINED SPOOL-HOLDER AND STOP-MOTION FOR BRAlDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 469,974, dated March 1, 1892. Application filed October 7, 1891. Serial No. 408,008. (No model.)

To all whom it may concern.-

Be it known that I, WILHELM MUNDT, a citizen of the United States, and a resident of the city of New York, in the county of-New York, in the State of New York, have invented certain new and useful Improvements in a Combined Spool-Holder and Stop-Motion for Braiding-Machines, of which the following is a specification.

The object of my invention is to provide a new and improved combined spool-holder and stop-motion device for that class of'braidingmachines known as the Hercules Braiding- Machines, and in which a series of fixed spool-holders are provided, around which movable spool-holders travel in serpentine slots.

The invention consists in the combination,

with a movable spool-holder, of a winged hub mounted to move vertically on the spoolholder, means for holding said winged hub adapted to trip and turn said hub to permit it to drop, a ring on the frame-plate of the braiding-machine, "which ring is provided with pins on which the lugs of the hub can act,

and a stopping and starting gear operated from said ring.

The invent-ion also consists in the construction and combination of parts and details,

I which will befully described hereinafter, and

finally pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of the fixed and movable spoolholder, parts being broken out and others being in' section. Fig. 1 is a face view of part of the standard. Fig. 2 is-a vertical transverse sectional view of the movable spoolport.

holder shown in Fig. 1. Fig. 3 is a sectional plan view on the line 3 3 of Fig. 1. Fig. 4 is a top view of the sliding stop-motion hub. Fig. 5 is a vertical longitudinal section of the same. Fig. 6 is a vertical longitudinal sectional view of the fixed spool. Fig. 6 is a detail view of the tension-eyes and their sup- Fig. 7 is a plan view of the base-plate of the braiding-machine, parts being in section. Fig. 8 is a vertical transverse sectional view on the line 8 8 of Fig. 7. Fig. 9 is a detail vertical sectional view on the line 9 9 of Fig. 8.

Similar letters of reference indicate corresponding parts. I

The top plate A of the braiding-machine is in which the fixed spool-holders are fastened, said apertures A being surrounded by the serpentine slot or track A A ring A is arranged along the edge of the circular baseplate A, and is suitably guided by lugs 13', and is provided on its inner surface with a series of pins B and with a cam-plate (J. A handle 0' projects from the outer surface of said ring, and is to be used for shifting the same. A lever D is pivoted on the standard D on the base plate A of the machine, and is provided at one end with a fork D embracing a collar E of the vertically-movable member of clutch E on the driving-shaft E, which clutch when raised throws the machineout of gear with the driving-shaft and when lowered throws it in gear. A spring D secured to the base-plate A presses the forked end of the lever D upward, and thus has a tendency to press the other enddownward, which other end is provided with an upwardly-projecting rod F, provided at its upper end with a laterally-projecting pin F, that is adapted to rest upon the top edge of the camplate'O. All these parts are old and well known, and are used in the braiding-machines.

The traveling spool-holders consist of the angular spindle G, on which the angular sleeve G is mounted to slide, said sleeve being pressed upward by the helical spring G ,surrounding the spindle and arranged between the lower end of the sleeve G and the basepiece G of said spindle, which base-piece is flanged and travels in the slots A in the usual manner.

At the upper end of the sleeve Gthe hub H is mounted on the spindle and is provided with two laterally-projecting beveled lugs H, each having a pin H on its upper surface, said hub being provided with a circular recess I, projecting down to about one-half the depth of the same, and in the bottom of said recess an aperture 1' is formed in the hub, which provided with a circular row of. apertures A,

aperture 1 has the same cross-section as the sleeve G ,but is made larger to adapt the upper end of said sleeve to pass into the same. The spool J rests upon the adjustable collar K, being provided with a neck K, projecting from its under side and into the circular recess I of the hub H.

The movable spool-holder-is provided :With the usual thread-guide and tension device that are old and well known and need not be described here.

The fixed spool-holder consists of a standard L, provided with two brackets L', in which the spindle M is mounted5thatpasses through the spool O. The standard-his providedwwith, the eyes a and 12, arranged a greater orless distance from each other, and between, the same a series of eyes dare arranged on a serpentine line on said standard. Aslide pIate N, provided with the wings N, is mouutedon the standard L and is provided iwith the upwardly-projecting wing N havingan aperT turethrough whichthe thread can pass, The spool O is provided atthe top arid bottom with the grooved flange 0.

P is a spring-wire secured to therbracketL and having its free end resting in the groove of the top flange, of the spool so as to act as a drag or brake to prevent the spool from rotating too rapidly and the thread from unwinding too rapidly. I

The thread on upon the spool O is passed through the bottom aperture, ct of the stand ard L and through the aperturein the wing N of the slide-plate Ni and through the up per aperture 1) of the standard L,andthus as long as the thread is not broken theslideplate N is held raised, as shown inF ig l, aboveihe lugs H of the hub H, Accord ingly, as more or less tension is requiredfor the thread 111, it can be passed through 7 one or more of theeyes d, which are arranged in azigzag line, as shown in Fig. 6.

The operation is as follows: When the na-V chine is in operation, the clutch is lowered and the pin F of the rod F rests upon thetop .edge of the cam-piece C and thehnoyable spool-holders travel in the serpentinetracks or slots A around the fixed" spool-holders. The hub H is in araised position andrrests upon the upper edge of thesleeyeG, said hub standing at an angle of ninety degrees to the sleeve G'that is to say, each diago-. nal axis of the hub H is at right angles to the corresponding diagonal axisof the sleeve G'.

The pins H on the upper end of theihub bear against the under side of the-collar K, the neck K of which is within the circular recess I of the hub. In case a thread ona fixed spool breaks, the corresponding plateN drops until it rests upon the bottom bracket L, and:

asiits projecting wings N are in the track of the lugs H of the several movable spools the lug H of the first movablespool, arriving at the fixed spool, at whioh thit plate: N. has; pp sms n t n he w ngso the plate N, whereby the hub is turned axially ninety degrees, so that thesides of its angular aperture I are now in line with the sides of the sleeve G and in consequence thereof the hub I-I drops to the bottom of the spindle Grand rests on the base G? of the same, as shown in dotted lines in Fig-1; and when it arrives at one es the pins B of the ring B on the plate A it strikes against such pin 3? and moves the ringB in the direction ofthe arrow X, Fig. 7: Thereby the campiece 0 is shifted from under the pin I of the rod F of the levertD, permitting the spring D of said lever D to throw upward the forked end of saidlever, whereby the clutch is shifted in such a manner as to disengage the operating mechanism ofthe machine from the drivingshaft, and thus the machine is vstopped. After .T ev ok r een i d anddrew upto raise the slide-plateNithehuh His raised to the top of the sleeve Daudthenis turned ninety, degrees, when: the, machine is, again started by shifting the-,ringfi in the inveise flil'ectionjof the a row Xtwherehn ee er edge of the cam-piece 0 acts onithe-f n h of the lever D, wherebyttheiforked end olf the lever D is lowered andthe;clutch brcug'htin T r with the r v ng-sh mans thus therm chine begins to operate.

Having thus described myinvention, I cl aim as new and desire to secure by Lettersliat' ent- 1.
